awesome-agent-skills is a curated collection of over 1,100 agent skills contributed by official engineering teams — Anthropic, Google, Vercel, Stripe, Cloudflare, Netlify, HashiCorp, Trail of Bits, Sentry, Hugging Face, Figma, Expo, and others. Each skill is vetted and works across Claude Code, OpenAI Codex CLI, Gemini CLI, and Cursor. VoltAgent is explicit that this is "hand-picked, not AI-slop generated." The project fills a gap that's emerged as agentic coding platforms have proliferated: each platform has its own skill/command format, and developers end up rebuilding the same auth flows, API integrations, and test harnesses for each one. awesome-agent-skills provides a universal, cross-platform skill layer maintained by the companies that built the APIs being automated. As of this week, the repo is trending on GitHub with 139 new stars today, bringing the total to 16.9k with 1.8k forks. VoltAgent also maintains companion repos: awesome-openclaw-skills (5,400+ skills for Claude Code specifically) and awesome-ai-agent-papers. For developers building on any agentic coding platform, this is quickly becoming the first stop before writing a custom integration from scratch.

Pretty Fish is a free, open-source Mermaid diagram editor with live preview, 5 built-in themes, multi-page workspaces, and one-click SVG/PNG export. It works offline as a Progressive Web App (PWA) and requires no account, no login, and no installation. It supports all 14+ Mermaid diagram types including flowcharts, sequence diagrams, Gantt charts, entity-relationship diagrams, and Git graphs. The editor includes syntax highlighting, auto-completion, instant error feedback, and a clean split-pane layout. The multi-page workspace lets you manage entire diagram projects in a single session. Export quality is excellent — SVG output is clean and scaling-ready for use in presentations, docs, or design systems. Pretty Fish hit Hacker News front page today with 128 points and has the makings of the go-to Mermaid editor for developers who generate diagrams from AI-assisted documentation workflows. With LLMs increasingly generating Mermaid syntax in their outputs, having a polished renderer and editor matters more than ever.
Reviewer scorecard
“Official skills from the companies that built the APIs are a different category from community-written scripts. When Stripe's own team ships a payments agent skill, I trust it handles edge cases my homegrown version would miss. This is the npm registry for agentic coding.”
“The official Mermaid live editor is clunky and slow. Pretty Fish loads instantly, works offline, and the multi-page workspace means I can manage all my architecture diagrams in one place. Bookmarking this immediately as my default Mermaid editor.”
“1,100+ skills sounds impressive until you realize most of them are thin wrappers that call the same APIs you'd call directly. 'Official' doesn't mean secure or well-maintained — a star count and corporate logos are not a substitute for auditing skills you're giving your AI agent.”
“It's a genuinely nice editor but it's solving a niche problem — most devs who need Mermaid diagrams already use VS Code extensions or embed them in Notion. And with no backend, there's no collaboration or sharing story, which limits its use in team workflows.”
“The emergence of a skills marketplace with official vendor buy-in is a structural shift: the agentic coding ecosystem is maturing from 'DIY everything' to 'pull from a curated catalog.' This is the infrastructure layer that makes agentic development teams viable at scale.”
“As AI tools increasingly output Mermaid syntax to explain architectures and flows, the need for a great rendering environment grows. Pretty Fish positions itself at the intersection of AI-generated diagrams and human editing — that's a well-timed niche.”
“Figma's presence in the contributor list is what gets my attention. Cross-platform creative workflow automation via official agent skills — rather than fragile screen-scraping hacks — is a meaningful step toward AI-assisted design pipelines that actually hold up.”
“Five beautiful themes and clean SVG exports mean I can finally use Mermaid diagrams in client-facing presentations without them looking like developer scratch notes. This is the Mermaid editor I've always wanted and the zero-friction setup seals it.”
